I have recently downloaded Graal PC. When I log in my account at the top it will say for example Graal64635. And when I log into a server it says Graal64645 has logged in.But when I click on my profile my name is Wolver. How do I change the account to Wolver permanently.  

You can't change your account name, however you can change your community name by purchasing gold.  

Account names used to be changeable but that changed a few years ago. Servers are now supposed to use community names or nicknames when displaying player information(like in a high score list or announcement).


You can change your commmunity name at the website, but choose wisely as you can only change it once. Also your nick can be changed at any time using the setnick command at any time as long as the server has it enabled and you're not in an area or event where it's disabled.  

Yeah you can't. Just say "setnick Wolver" and your name will change to Wolver.
